February 2, China Mobile Zhejiang Branch officially launched 4G business in Hangzhou and Wenzhou. China Mobile has also been experimenting with 4G networks in Beijing, and a handful of users are currently experiencing tests. Guangdong Mobile will be revealed before and after the Lantern Festival in Guangzhou, Shenzhen and the two synchronized open scale unprecedented 4G experience activities, will soon be tested commercial.
Commercial newspaper reporter from Shanghai Mobile learned that its 4G experience activity has not yet been carried out. The latest news is that in the first half of 2013, Shanghai will be built LTE large-scale test network. At that time, the city includes the inner ring within 190 square kilometers of the region to achieve seamless LTE network coverage.
4G to achieve speed leap
Reporter learned that the Zhejiang Mobile February 2 began in Hangzhou and Wenzhou Two cities in China's independent 4G network LTE network, this is the first time in China to conduct the scale of the 4G business trial commercial.
It is understood that, as the first trial commercial city, Zhejiang Mobile has been in Hangzhou, Wenzhou to individual and enterprise users fully open 4G business, while Zhejiang Mobile also opened in Ningbo, 4G experience activities, the three cities LTE users can achieve the same flow rate between the city of 4G roaming network. However, from Hangzhou, Wenzhou, the trial commercial, the use of terminals mainly include LTE high-speed Gateway and Internet Companion (MiFi), they can convert 4G network signal to Wi-Fi signal, and more popular 4G mobile phone and internet card is still not launched. Zhejiang Mobile said it is expected that by March this year, the support of the LTE network 4G mobile phones are expected to put into use.
The LTE adopted by China Mobile is China's independent 4G network Standard and one of the international two universal 4G standards. From the current measured speed of LTE network in Hangzhou, its download speed can be more than 100Mbps, is the current 3G internet speed of several times.
Shanghai trial business waits for unified command
"In the first half of this year Shanghai will be built 4G large-scale test network, but when commercial still need to wait for the communications authorities unified command." "said the Shanghai mobile related person.
In Shanghai communications industry "Twelve-Five" Planning (2011-2015), there is such a statement: "Further promote the LTE, 4G and other new broadband wireless communications technology continued research and development and application, the LTE industry chain is maturing, ' Twelve-Five ' in the middle and late will be expected to start large-scale commercial deployment." ”
4G trial business to meet three conditions: network construction, terminals in place, market environment mature. The above mobile Personage told the newspaper reporter.
It is understood that up to now Shanghai has opened 110 LTE base station, the realization of Zhangjiang high-tech Park, Lujiazui Financial District, Pudong South Road, such as 3 areas of the outdoor film continuous coverage. In the first half of 2013, Shanghai will build LTE large-scale test network. At that time, the city includes the inner ring within 190 square kilometers of the region to achieve seamless LTE network coverage.
"2013-year expansion of the scale of the test network is mainly for trial commercial, planning to achieve within the inner ring and outside the focus area of the entire coverage, base station scale of more than 1000." Outdoor mainly covers Shanghai's central business, commercial district, administrative area, University Park and High-tech Park and other key areas, indoor mainly covering government office buildings, 5 A-level office buildings, flagship stores and large exhibition center and other key buildings. "Shanghai Mobile said.
Cross-examine 4G
1 4G and 3G changes?
A: China Mobile LTE is China's independent innovation 4G Technology, is the fourth generation of mobile communications, one of the two major international standards. Its network can provide the highest download rate of 100M per second, the highest upload rate of 50M per second.
2 What is the difference between the maximum rate and the actual rate?
Answer: The 100M download rate per second is the theoretical value in the experimental environment. In the actual commercial situation, the domestic 4G commercial speed still remains to be seen. In this respect, professionals say that mobile networks use public access, with a certain number of restrictions, if the number of users in a certain area overload or use a large number of large-capacity network applications, the actual rate will be affected.
According to public media reports, in South Korea, the 4G network speed average 500kb/s, equivalent to 4Mbps; in the United States, Technology Web site PCMag for the sprint 4G rate test results of 2. 99Mbps.
In this connection, the Shanghai Mobile Integrated department related Personage said, the current 4G terminal specification only supports 80Mbps, the measured single terminal may reach the downlink 80Mbps. When you want to try commercial or formal commercial, will give certain guarantee speed.
3 4G Network, do not need broadband?
A: Hangzhou Mobile launched 4G experience business, including a book size of the 4G high-speed wireless gateway to work, "Do not pull the network cable, go where directly connected to the power can be used." "It is understood that the ordinary wireless gateway can support up to 6 computers online, and cafes and other public places such as the installation of special wireless gateway can support 20 of computers online."
Does this mean that fixed-network broadband becomes redundant?
To this, Shanghai mobile related Personage said, the mobile network has the innate advantage and so on free flexibility, but also may encounter the signal coverage, the frequency resource scarcity and so on limits. "4G network depends on the cell signal." 4G generally more suitable for liquidity, temporary Internet demand, is the extension of 3G network. But overall, mobile replacement fixed will be the trend of the development of the Internet. ”
4. What time is the 4G licence issued?
A: In March 2012, Ministry of Industry Minister Wei said that 4G license issuance also needs years time, LTE development to solve the base station and terminal two major problems. In September 2012, Wei's claims changed, saying he would issue 4G licences within a year or so.
There is a view that the 4G licences are expected to be issued within the year. April 1, 2008, China Mobile in the domestic launch of the 3G trial commercial, January 7, 2009, the Ministry of Commerce issued a 3G license to the three major operators. It lasted 9 months.
Telecommunications expert Xiang that in 2013, 4G licences are likely to be issued, "4G license is not yet issued because the Ministry of Industry is considering the balance of several operators." Because mobile has 700 million users and hundreds of billions of dollars, one license, the advantages appear. is now in a delicate game. ”
5 4G times will the tariff drop?
A: China Mobile said, from the current Hangzhou 4G network measured speed, download speed can exceed 100Mbps, is currently 3G Internet speed of dozens of times times. From the tariff standards, it is also significantly lower than the current market 3G package price, of which the monthly 2G flow cost of 50 yuan, 100G flow cost of 500 yuan. Mobile previously said that 4G tariffs will not be more expensive than 3G.
JPMorgan's analysis argues that it is not easy to make the transition to new, more capacity networks, and that the only way is to lower the tariffs on new networks.
